Resource Adequacy


Available EPRI Tools to Support Adequacy Practitioners


Resource Adequacy Viewer Tool

Resource Adequacy Viewer Tool (or RAVT) is a calculator and a visualization tool developed at EPRI to analyze results from any RA model. RAVT reads and analyzes RA model outputs and creates visualizations for various RA metrics. It also categorizes shortfall events based on whether constraints arise from:

  • Capacity limitations,
  • Energy constraints, or
  • Both capacity and energy constraints
